Present study was undertaken to assess the extent of heterosis for seed cotton yield and its attributing traits in 54 inter plant type hybrids of cotton developed by crossing 9 lines with 6 testers in line tester mating design during Kharif 2009 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. The mean sum of squares of parent's vs hybrids was significant for all the characters except reproductive points and boll harvest index, indicating presence of heterosis for these traits. None of the crosses were superior for all the traits studied. However, the cross L5 x T5 was the best as it had highest mean performance for economically important characters. Majority of the crosses exhibited positive significant mid parent, better parent heterosis for all important yield contributing characters except for inter boll distance and inter branch distance where they showed significant negative heterosis, indicating predominance of non-additive gene action in the genetic control of these traits. Most of the hybrids expressed significant standard heterosis for all the characters over the checks.Keywords

A field experiment was carried out to formulate an economic weed management stratergy in vegetable cowpea during Kharif 2012-13 and 2013-14 at the All India Co-ordinated Vegetable Improvement Project in the Regional Horticultural Research and Extension Center, Dharwad. The results based on two years pooled data revealed that, weed control treatments mulching with black polythene and pendimethaline @1 kg/ha + one hand weeding 30 DAS, provided effective control of weeds and significantly increased pod yield of vegetable cowpea over weedy check. The highest net returns (Rs.36211ha-i) and B:C ratio (1.75) was registered with pendimethaline at 1 kg/ha+ One hand weeding 30 DAS. Profit, with mulching with black polythene were less due to higher cost of black polythene.Keywords
